Appliance Error Code Lookup
Find your appliance's error code below to understand what it means and what to do next.
LG Error Codes
Er 22— The Er 22 code means the compressor relay (also called the start relay or inverter board relay, depending on your model) has failed. The relay is responsible for sending the correct startup signal to the compressor. Without it, the compressor clicks, hums briefly, and shuts off, or it does not attempt to start at all. The refrigerator loses all cooling. This is one of the more serious error codes because no cooling occurs while the relay is down.
Er 67— The Er 67 code means the refrigerator has detected that a door is not fully closed or a gap exists between the door and the cabinet. LG refrigerators use door switches and, on some models, magnetic reed sensors to detect door position. If a door stays ajar or the gasket does not seal, the board triggers Er 67 after a set time (usually 5 minutes). The alarm also sounds to alert you. Leaving a door open causes rapid temperature rise, frost buildup, and compressor overwork.
Er CF— The Er CF code tells you the condenser fan motor is not running. This fan sits near the compressor at the bottom-rear of the unit. It pulls air across the condenser coils to dissipate heat. Without it, the compressor overheats and shuts down. Your refrigerator stops cooling entirely.
Er CO— The Er CO code indicates the main control board and the display board have lost communication with each other. These two boards exchange data through a ribbon cable or wire harness. If that link breaks, the display cannot send your temperature commands to the main board, and the main board cannot report status back. The refrigerator often continues running at default settings, but you lose all user controls.
Er dH— The Er dH code means the defrost heater circuit is not working. During automatic defrost cycles, the control board sends power to a glass-tube or calrod heater mounted beneath the evaporator coils. This heater melts accumulated frost. If the heater, its wiring, or the defrost control circuit fails, frost builds up on the evaporator until airflow is completely blocked. The freezer warms up first, then the fresh food section follows.
Er FF— The Er FF code means the main control board is not receiving a rotational signal from the freezer evaporator fan motor. The fan is either stalled, electrically failed, or its wiring harness is damaged. Without this fan, cold air cannot circulate through the freezer and fresh food compartments. Temperatures rise fast, usually within a few hours.
Er FS— The Er FS code means the freezer temperature sensor (thermistor) has failed. This sensor is a small bead or probe mounted on or near the evaporator that reports the freezer temperature to the main control board. A shorted or open sensor sends an incorrect reading, causing the board to run the compressor too much, too little, or not at all. You get a freezer that is either too warm or frozen solid.
Er gF— The Er gF code means the refrigerator is not detecting water flow to the ice maker or water dispenser. The flow sensor in the water supply line is reading zero flow when the system expects water. This shuts down ice production and blocks the water dispenser. The problem is either a supply-side issue (no water getting to the fridge) or a component failure inside the refrigerator.
Er HS— The Er HS code means the humidity sensor inside the refrigerator has sent an out-of-range reading to the main control board. This sensor monitors moisture levels in the fresh food compartment and adjusts fan speed and damper positions to reduce condensation and keep produce fresh. A failed sensor leads to excess condensation, water pooling inside the fridge, or overly dry conditions that wilt produce.
Er IF— The Er IF code indicates the ice maker fan motor is not spinning or the control board is not receiving a speed feedback signal from it. This fan circulates cold air around the ice maker compartment to maintain proper freezing temperatures. Without it, ice production slows dramatically or stops entirely. The rest of the freezer and fridge continue to function normally in most cases.
Er IS— The Er IS code means the ice maker temperature sensor (thermistor) is reading outside its expected range. This sensor tells the main board when the ice maker mold is cold enough to begin a harvest cycle and when to fill with water. A bad sensor stops ice production because the board either never triggers a harvest or never opens the water valve to fill the mold.
Er IT— The Er IT code means the ice maker motor cannot complete its harvest cycle. The motor rotates the ice tray or ejector arms to dump ice into the bucket. If the motor stalls, the tray jams, or the ejector arms cannot rotate, the board detects the failure and displays Er IT. Ice production stops until the jam is cleared or the motor is replaced.
Er rt— The Er rt code means the room temperature sensor has failed or is sending readings outside its normal range. This sensor measures the ambient temperature around the refrigerator. The main board uses this reading to adjust compressor run time, defrost intervals, and fan speeds based on the room conditions. A failed sensor causes the board to use incorrect assumptions, leading to overcooling, undercooling, or excessive energy use.
Er SS— The Er SS code means the pantry or fresh food compartment temperature sensor (thermistor) has shorted. A shorted sensor sends a near-zero resistance reading to the main board, which the board interprets as an extremely high temperature. The compressor runs continuously trying to cool the compartment, leading to frozen food in the fridge section, excess frost, and high energy bills.
AE— The AE error code means the leak sensor in the base pan of your LG washer has detected water. A float switch or moisture sensor at the bottom of the unit triggered the alert. The washer stops the cycle and activates the drain pump to remove standing water. This error requires immediate attention — water is actively leaking inside the machine.
CE— The CE error code means the main control board is detecting excessive or abnormal electrical current flowing to the drive motor. The board shuts down motor operation immediately to prevent damage. This is a protective response — something in the motor circuit is drawing more current than the board expects. The washer will not spin or agitate until the problem is resolved.
CL— The CL display on your LG washer is not an error code. It means the child lock feature is activated. The washer ignores all button presses except the Power button. The door stays locked, and you cannot change cycles, start, or pause. This is a safety feature designed to prevent children from altering the cycle or opening the door during operation.
dE— The dE error code signals that the door lock switch is not engaging. Your LG washer refuses to start any cycle until the door is securely latched and the lock mechanism confirms a closed position to the control board. The dE1 variant points to the lock mechanism itself, while dE2 relates to the door switch circuit.
dE2— The dE2 error code means the door lock switch circuit is intermittent. The control board detects the door lock signal dropping in and out during a cycle. The washer interprets this as the door opening and closing repeatedly, which is a safety risk during spin. The cycle stops immediately. Unlike the general dE code, dE2 specifically points to the electrical side of the door lock — the switch or its wiring — rather than the physical latch.
EE— The EE error code means the EEPROM chip on the main control board cannot be read or written to. EEPROM stores your washer's operating parameters, cycle data, and calibration values. The washer cannot function without this data. This is a board-level failure, and the machine will not run any cycle until the board is repaired or replaced.
FE— The FE error code means water continues flowing into the tub after it should have stopped. The water level pressure switch detects the tub is overfilled and triggers the error. The washer activates the drain pump to prevent flooding. A stuck-open water inlet valve is the primary cause. This error requires immediate attention to prevent water damage.
IE— The IE error code means your LG washer is not receiving enough water. The machine expects the tub to reach a set water level within a specific time. If it does not, the washer halts the cycle and displays IE. No water enters the drum, or it trickles in too slowly to register.
LE— The LE error code means the washer drum is not spinning because the direct-drive motor is overloaded, locked, or has a sensor failure. The control board detects that the rotor is not turning despite sending power to the stator. The washer stops the cycle to protect the motor from burnout. LE1 specifically indicates a problem with the motor's hall sensor.
nE— The nE error code means your LG ThinQ-enabled washer cannot connect to your home WiFi network. The washer's built-in WiFi module failed to establish or maintain a connection to your router. This error does not prevent the washer from running cycles manually. It only affects smart features: remote start, cycle monitoring through the LG ThinQ app, and smart diagnosis. The nE1 variant indicates the WiFi module itself has a hardware fault.
OE— The OE error code on your LG washer means the machine tried to drain the water but failed. The washer gives itself about 10 minutes to empty the tub. If water remains after that window, the OE code appears and the cycle stops. Standing water stays in the drum until you fix the blockage.
PE— The PE error code means the water level pressure switch is not communicating correctly with the control board. The washer cannot determine how much water is in the tub, so it refuses to start or stops mid-cycle. The pressure switch uses a small air hose connected to the tub — as water rises, air pressure in the hose increases and the switch registers the level. A break anywhere in this system triggers the PE code.
PF— The PF error code means your LG washer lost power during a running cycle. A power outage, tripped breaker, or loose plug interrupted the electrical supply. The washer remembers it was mid-cycle and displays PF when power returns. This is not a mechanical failure — it is the washer telling you the cycle did not finish.
tCL— The tCL display is a maintenance reminder, not an error code. Your LG washer is telling you to run a Tub Clean cycle. LG washers track the number of wash cycles completed and display tCL after approximately 30 cycles. Residue from detergent, fabric softener, and body oils builds up inside the outer tub and door seal, creating odor and mold. The Tub Clean cycle uses hot water and high spin speeds to flush this buildup.
tE— The tE error code means the washer's temperature sensing circuit has a problem. The thermistor (temperature sensor) is sending out-of-range readings to the control board, or the heater circuit is open. The washer stops the cycle to prevent overheating or washing at the wrong temperature. The sub-codes indicate specific faults: tE1 is a thermistor reading error, tE2 is a heater circuit failure, tE3 is a sensor communication error, and tE4 relates to a secondary thermistor.
UE— The UE code means the washer drum is spinning unevenly and the machine cannot reach full spin speed. LG displays a lowercase "uE" while it tries to rebalance automatically. If it fails after several attempts, the code changes to uppercase "UE" and the cycle stops. Clothes remain wet because the final spin never completes.
Samsung Error Codes
14E— Error code 14E indicates the secondary ice maker sensor has failed. Samsung refrigerators with dual ice makers (one in the door, one in the freezer compartment) use separate sensor circuits. The 14E code specifically targets the secondary unit. The ice maker tied to this sensor stops producing ice. On newer Samsung models, the display reads 14C.
1E— Error code 1E tells you the refrigerator compartment temperature sensor has lost communication with the main control board. The sensor either reads out of range or sends no signal at all. Your fridge stops regulating temperature correctly, and food spoilage starts fast. On some Samsung models, this same fault shows as 1C or SE on the display.
21E— Error code 21E means the freezer evaporator fan is not spinning or the control board receives no rotational feedback from the fan motor. This fan circulates cold air from the evaporator coils throughout the freezer and into the fridge compartment. Without it, temperatures rise in both compartments even though the compressor runs normally. Newer Samsung models display this as 21C.
22E— Error code 22E indicates the fridge compartment fan is not running or a door has been left open too long. Samsung triggers this code when the fan's feedback signal is absent or when the door switch reports an open door for an extended period, causing the fan to shut off. The fresh food section warms up while the freezer often remains cold. On newer models, the code reads 22C.
24E— Error code 24E means the freezer defrost cycle did not complete successfully. The control board started a defrost cycle, but the evaporator temperature did not rise to the expected level within the allotted time. Ice builds up on the freezer evaporator, blocks airflow, and causes both the freezer and fridge to warm up. On newer models, the code shows as 24C.
25E— Error code 25E means the fridge compartment defrost cycle did not complete. The fresh food side evaporator did not reach the required temperature during defrost. Ice builds up behind the rear panel in the fridge section, blocking airflow and causing the fridge to warm up while the freezer stays cold. Newer Samsung models show this as 25C.
2E— Error code 2E means the freezer compartment temperature sensor has failed or lost its connection to the main control board. The freezer cannot maintain correct temperatures. Food thaws or the compressor runs nonstop trying to compensate. On newer Samsung models, this code displays as 2C.
33E— The 33E error code means the ice pipe heater inside your Samsung refrigerator has failed or lost connection to the main control board. This heater prevents the water supply line to the ice maker from freezing. Without it, water stops flowing to the ice maker and ice production halts completely. You will also see this displayed as 33C on some Samsung models.
39E— The 39E error code signals a general ice maker malfunction in your Samsung refrigerator. The main control board detected that the ice maker is not completing its harvest cycle — the process of freezing water, ejecting ice cubes, and refilling the tray. This code covers multiple possible failures within the ice maker assembly itself. Some Samsung panels display this as 39C.
40E— The 40E error code means the ice maker fan motor has stopped working or is not reaching the correct speed. This fan circulates cold air over the ice mold to accelerate freezing. Without it, ice production slows dramatically or stops entirely. The display shows 40C on some Samsung models — same fault, same fix.
41E— The 41E error code tells you the ice bucket full sensor (also called the ice level sensor) is malfunctioning. This sensor uses an infrared beam or mechanical arm to detect when the ice bucket is full. When the sensor fails, the ice maker either stops making ice because it thinks the bucket is full, or it overproduces ice and jams. Samsung also displays this as 41C on certain models.
44E— The 44E error code means the ice tray twist motor is not completing its rotation. This motor twists the ice tray to eject frozen cubes into the bucket. When the motor stalls, jams, or fails electronically, the control board throws 44E (or 44C on older models). Ice production stops until the motor issue is resolved.
4E— Error code 4E means the freezer defrost temperature sensor has failed. This sensor monitors evaporator temperature during the defrost cycle to prevent overheating or incomplete defrosting. Without it, the defrost heater runs too long (risking water leaks) or not long enough (causing ice buildup on the evaporator). Newer Samsung models display this as 4C.
5E— Error code 5E signals that the fridge compartment defrost sensor is malfunctioning. This sensor tracks evaporator temperature on the fresh food side during defrost cycles. A failed sensor causes incomplete defrosting, frost buildup behind the rear panel of the fridge section, and reduced cooling. Newer Samsung displays show this as 5C.
6E— Error code 6E indicates the ambient (room) temperature sensor is not sending a valid reading to the main control board. This sensor tells the fridge how warm the surrounding room is so it can adjust compressor and fan speed accordingly. A failed ambient sensor causes the fridge to run inefficiently -- overcooling in a warm kitchen or undercooling in a cold garage. On newer models, this displays as 6C.
84E— The 84E error code means the compressor is mechanically locked or electrically stalled. The control board sent the start signal, but the compressor did not begin running within the expected timeframe. This is a serious fault — without the compressor, your refrigerator cannot cool at all. The code displays as 84C on some Samsung models. Your fridge and freezer temperatures will rise until this is fixed.
85E— The 85E error code means the main control board has lost communication with the compressor inverter board. These two boards exchange data constantly to regulate compressor speed and cooling output. When the communication link breaks, the compressor shuts down and the refrigerator stops cooling. Samsung displays this as 85C on some models. Your food is at risk — act fast.
88 88— The 88 88 display on a Samsung refrigerator means every segment of the digital display is lit at once. This happens in two situations: during the initial display test when the refrigerator first powers on (normal and lasts 2-5 seconds), or after a power surge that locked up the control board (not normal if it persists). If 88 88 stays on the display for more than a minute, the main control board is stuck in a boot loop or has been damaged by the power event.
8E— Error code 8E means the ice maker temperature sensor is not responding correctly. This sensor monitors the ice tray temperature to determine when water should fill and when ice is frozen enough to harvest. A failed sensor stops ice production entirely or causes the ice maker to cycle nonstop without producing usable ice. On newer models, this shows as 8C.
AP— The AP display on your Samsung refrigerator is not an error code. AP stands for Access Point mode. The refrigerator's WiFi module has been activated and is broadcasting its own wireless signal so you can connect it to the Samsung SmartThings app. This mode is used during initial WiFi setup or when reconnecting the fridge to a new wireless network. Your refrigerator continues cooling normally while AP mode is active.
OF OF— OF OF on your Samsung refrigerator display means the unit is in Demo Mode (also called Cooling Off Mode or Shop Mode). In this mode, the lights and display work normally, but the compressor and fans are turned off. The refrigerator is not cooling at all. Retail stores use Demo Mode to display the fridge on the showroom floor without running the cooling system. This mode also activates accidentally when certain button combinations are pressed during cleaning or by children. Your display shows OF OF, O FF, or OFF depending on the model.
PC ER— The PC ER error code means the main control board and the display panel board have lost communication with each other. These two boards are connected by a ribbon cable or wire harness, and they need constant two-way data exchange to operate the refrigerator. When the link breaks — often after a power surge or outage — the display shows PC ER (or PC CH on some models). The refrigerator usually continues cooling in its last known state, but you cannot adjust settings or temperatures from the display.
3E— Your Samsung washer displays 3E when the control board detects a motor malfunction. The board monitors the motor through a Hall sensor (also called a rotor position sensor) that reports the motor's speed and direction. When the sensor sends no signal, an erratic signal, or a signal that does not match the expected motor behavior, the washer stops and displays 3E. Sub-codes 3E1 through 3E4 narrow down the specific failure, but the troubleshooting approach covers all of them.
4E— Your Samsung washer displays 4E when it fails to fill with water within a set time. The control board expects a rising water level after opening the inlet valves. When the water level sensor detects no change, the cycle stops and the 4E code appears. The washer will not proceed until the water supply problem is resolved.
4E2— Your Samsung washer displays 4E2 when it detects that the incoming water temperature does not match the expected temperature for the selected cycle. Specifically, the washer asked for cold water but received hot, or vice versa. This happens because the hot and cold fill hoses are connected to the wrong inlet ports on the back of the machine.
5E— Your Samsung washer displays 5E when it cannot pump out the water within the allotted drain time. The control board monitors the water level sensor during the drain phase. If the water level does not drop within about 15 minutes, the cycle stops and the 5E code locks onto the display. Water remains in the tub until the drainage problem is fixed.
AE— Your Samsung washer displays AE when the main control board and the sub-board (also called the interface board or display board) lose communication with each other. These two boards exchange data constantly during operation. The main board manages motor, heater, valve, and pump control. The sub-board handles the user interface, buttons, and display. When the data link between them breaks, the washer cannot operate and displays AE.
CL— Your Samsung washer displays CL when the child lock feature is activated. This is not an error code. Child lock is a parental safety feature that disables all buttons except Power. The washer ignores all button presses and will not start a cycle while CL is active. The door also remains locked on front-load models. You simply need to deactivate the child lock to use the washer normally.
dE— Your Samsung washer displays dE when the door lock switch does not confirm that the door is securely latched and locked. The washer will not start a cycle unless the door lock assembly sends a closed-and-locked signal to the main control board. This protects against water leaks and prevents the door from opening during a spin cycle.
HE— Your Samsung washer displays HE when the heating element fails to raise the water temperature as expected. The control board monitors the thermistor readings during cycles that require heated water. If the water temperature does not increase within a set time after the heater is activated, or if the heater circuit draws abnormal current, the board stops the cycle and shows HE. Sub-code HE1 means the heater is not heating. HE2 means the heater is overheating (temperature exceeding 95 degrees C / 203 degrees F).
LE— Your Samsung washer displays LE when the control board detects water where it should not be or receives abnormal readings from the water level pressure sensor. The washer stops the cycle immediately to prevent water damage. This code has two distinct causes: an actual water leak reaching the leak sensor on the base pan, or a faulty water level pressure sensor (pressure switch) sending incorrect data to the control board.
OE— Your Samsung washer displays OE when the water level in the tub exceeds the maximum allowed level. The water level pressure sensor detects that the tub has overfilled beyond what the selected cycle requires. The washer stops the fill and displays OE to prevent water from reaching the door seal and spilling onto the floor. In most cases, the water inlet valve is stuck open or the pressure sensor is giving a false reading.
PE— Your Samsung top-load washer displays PE when the clutch position sensor reports an abnormal reading to the main control board. The clutch assembly in top-load Samsung washers shifts between wash (agitation) and spin modes. The position sensor confirms the clutch has engaged the correct mode. When the sensor signal is missing or out of range, the washer cannot safely transition between wash and spin phases.
PF— Your Samsung washer displays PF when it loses electrical power in the middle of a cycle and then regains it. The control board stores the cycle stage in memory. When power returns, the board detects that a cycle was interrupted and displays PF to notify you. The washer does not automatically resume the interrupted cycle. You need to either restart the cycle or select a new one.
Sud— Your Samsung washer displays Sud when the control board detects excess foam inside the drum. The washer uses a foam sensor or monitors motor load to detect suds buildup. Excessive suds reduce wash efficiency because the drum cannot agitate properly through thick foam. The washer pauses the cycle and waits for the suds to dissipate before continuing. If suds do not reduce after a waiting period, the code remains on the display.
tE— Your Samsung washer displays tE when the main control board receives an out-of-range reading from the water temperature sensor (thermistor). The thermistor is a small probe inserted into the outer tub or the heater housing that changes resistance as the water temperature changes. When the resistance reading falls outside the expected range, the board cannot regulate water temperature and halts the cycle.
UE— Your Samsung washer displays UE when the drum load is unevenly distributed during the spin cycle. The washer attempts to redistribute the load by tumbling at low speed up to three times. If the vibration sensor still detects excessive imbalance after these attempts, it stops the spin and displays the UE code. The washer is protecting itself and your floor from violent shaking.
